The effectiveness of job rotation to prevent work related musculoskeletal disorders: protocol of a cluster randomized clinical trial

The effectiveness of job rotation to prevent work related musculoskeletal disorders: protocol of a cluster randomized clinical trial

Methods/Design: A cluster randomized controlled trial will be used to investigate the effectiveness of job rotation to prevent musculoskeletal disorders in industrial workers. The randomized cluster was based in characteristics of production sectors. A total cluster will be 4 sectors, and 957 workers will be recruited from a textile industry and randomly allocated into intervention or control groups. Both groups will receive training on ergonomics guidelines. In addition, the intervention group will perform job rotation, switching between tasks with low, moderate, and high risk for musculoskeletal complaints. The primary outcome will be the number of working hours lost due to sick leave by musculoskeletal injuries recorded in employee administrative data bases. Secondary outcomes measured via survey include: body parts with musculoskeletal pain, the intensity of this pain, physical workload, fatigue, general health status, physical activity level, and work productivity. Secondary outcome measures will be assessed at baseline and after 3, 6, 9, and 12 months. The cost-effectiveness analysis will be performed from the societal and company perspective.

Modified method for evaluating weathering intensity using outdoor exposure tests on wood-based panels

Modified method for evaluating weathering intensity using outdoor exposure tests on wood-based panels

MOR and IB retentions were measured over 7 years of outdoor exposure tests at eight sites to study weathering intensity. Weathering intensity was determined based on the coefficient of correlation from linear regression analy- sis to give a logarithm of weathering intensity for each panel. Figure 6 shows the relationship between calculated weathering intensity and the mechanical property reten- tions of PB(PF) as a cobweb chart, and Fig. 7 shows the relationship between calculated weathering intensity and the mechanical property retentions of OSB(aspen) as a cobweb chart. In terms of IB retention, the coefficient of correlation’s sum of S (log P S), calculated using daily, 10-day, and monthly data, was lower than that of MOR retention. This implicates that sunlight hours as a factor positively related to panel surface deterioration, because IB is an interior property of panels, whereas MOR is a surface property. Using 10-day and monthly data, we found that the coefficients of correlation for relationships between P (P 9 S), P (T 9 P), and P (T 9 P 9 S) and IB reten- tion were high, especially for P (T 9 P), and P

Impact of Various Training Program on Selected Biochemical Variables among College Men Students

Impact of Various Training Program on Selected Biochemical Variables among College Men Students

Blood stream carries the main forms of fat called cholesterol and triglycerides. These fats are lipids come partly from food, partly from the body’s own production in the liver. Fats are not water soluble and hence cannot travel through the blood easily. With the help of lipoprotein, digested fat from the liver is carried to various parts of the body by the blood vessels. The cholesterol returns to the liver and repeats its job. The lipoproteins are packages of cholesterol placed in liver. Lipoproteins are made from lipids and proteins. There are mainly four kinds of lipoprotein packages namely chylomicrons, very low density of lipoprotein (VLDL), low density of lipoprotein (LDL), high density of lipoprotein (HDL). High density of lipoprotein has more protein content.

Geocoding rural addresses in a community contaminated by PFOA: a comparison of methods

Geocoding rural addresses in a community contaminated by PFOA: a comparison of methods

The current study is a secondary analysis of existing data with the goal of informing geocoding decisions for a large epidemiological investigation of the health effects of PFOA in a rural community. A strength of this study was the availability of GPS measurements, but a related weak- ness was that the existing data only included 135 rural addresses in Wood County, WV. Bearing in mind the small numbers, our analysis showed that the county E911 data table appears to perform better than the LACS data- base in ZP4, substantially converting more self-reported addresses. Although the E911 table did not include 7 of the self-reported pre-E911 addresses, the table did include other street addresses on the same street, so while the table may be incomplete, it is not missing entire streets. LACS ZP4 was able to convert 3 of the 7 addresses missed by the E911 table. Because ZP4 is already used to clean and standardize addresses, we rec- ommend also running the LACS database. While the return of additional addresses may be small, the amount of additional work is negligible.

Child Care Services, Socioeconomic Inequalities, and Academic Performance

Data from the Quebec Longitudinal Study of Child Development (QLSCD) were used. Through birth registries, the QLSCD selected 2120 singleton newborns representative of the Quebec (Canada) newborns between 1997 and 1998. This study was initiated during the implementation of CCS (family- or center-based settings) offered at low cost ($5 per day) to families throughout the province. Ethics approval and informed consent were obtained at each data collection year (5 months, 1.5, 2.5, 3.5, 4.5, and 12 years). Full information maximum likelihood (FIML) dealt with missing data when estimating our CCS trajectories and family variables ( N = 2120). Sample sizes varied thereafter for speci fi c outcomes and predictors. A total of 1077 (reading), 1137 (writing), and 1112 (mathematics) children had Quebec government examination data. 16 To address

Conformational changes in natural biopolymers induced by electromagnetic field and cadmium ion exposure

Conformational changes in natural biopolymers induced by electromagnetic field and cadmium ion exposure

Addition of cadmium ions into aqueous solution of DNA above maximum acceptable concentration (MAC) leads to a staged increase in fluorescence intensity and to an increase of cadmium concentration (Figure 3); this reflects the absence of DNA denaturation process in which fluorescence would have subsided [6]. Cadmium MAC in whole blood is reported by certain sources [16, 20] to be 0.007 μg/ml. Several plateaus are observed (Figure 3) on the curve illustrating an association between fluorescence intensity of DNA aqueous solution and Cd 2+ concentration in the solution at the points corresponding to Cd 2+ /DNA = 1:5; 1:2.5; 1:1. This demonstrates a discrete nature of changes in DNA structure associated with presence of cadmium ions in the solution. Possibly, cadmium ions build themselves into DNA double helix as an intercalating agent and zinc antagonist, which further leads to an impairment in nucleic acid metabolism, as it was described by some authors [1].

A ROBUST FRAMEWORK TO DETECT MOVING VEHICLES IN DIFFERENT ROAD CONDITIONS IN INDIA

This paper proposes an adaptive algorithm of intensity modify by power function and local contrast enhancement based on center-surround for color images enhancement that have low lightness. The proposed NFPE algorithm, inspired by the algorithms PNAE and NNAE is able to simultaneously enhance the image intensity and local contrast with better visual effects. The performance of the proposed NFPE algorithm has been compared in term of both visually and numerically with four previous methods. Experimental results show that the NFPE algorithm outperforms those four in terms of computational efficiency, also provides better visual representation in numeral comparisons.

Effects of Waterborne ZnO Nanoparticles and Zn2+ Ions on the Gills of Rainbow Trout (Oncorhynchus mykiss): Bioaccumulation, Histopathological and Ultrastructural Changes

Effects of Waterborne ZnO Nanoparticles and Zn2+ Ions on the Gills of Rainbow Trout (Oncorhynchus mykiss): Bioaccumulation, Histopathological and Ultrastructural Changes

Johnston et al. (2010) studied the Zn bioaccumulat ion in zebrafish gills (Danio rerio) and found no significant bioaccu mulat ion of this ele ment after 14 days of exposure to 500 and 5,000µg/L ZnO NPs. Hao et al. (2013) reported that 50mg/L o f nano- ZnO can caus e more severe histopathological alterations than what the same concentration of bulk - ZnO may do. This was main ly due to the induction of higher levels of intracellular o xidative stress. Because of their tiny size, NPs can cross the small intestines and distribute further into other tissues (De Jong et al., 2008). Kaya et al. (2015) e xposed tilapia (Oreochromis niloticus) to small (10-30n m) and large (100n m) Zn O NPs and found higher accumu lation of small Zn O NPs in various tissues (including gills). Fan, Li, Yang, and Zhang (2013) showed that Zn bioaccumulat ion in different tissues of goldfish (Carassius auratus) depends on types of Zn (ZnO NPs, bulk Zn O, and Zn 2+ ). However, more researches are still required to understand the exact mechanis ms of toxic ity caused by each types of Zn in diffe rent organs of aquatic organisms.

Prenatal and postnatal antibiotic exposure influences the gut microbiota of preterm infants in neonatal intensive care units

Prenatal and postnatal antibiotic exposure influences the gut microbiota of preterm infants in neonatal intensive care units

in an increase in Staphylococcus, Streptococcus, Serratia, and Parabacteroides, constituting potentially pathogenic communities [15]. Fouhy et al. found that postnatal anti- biotic subject exposure (ampicillin and gentamicin within 48 h of birth) resulted in significantly lower levels of Bifi- dobacterium and Lactobacillus than in untreated controls 4  weeks after the cessation of treatment [16]. Antibiot- ics are the most commonly prescribed medications in NICUs. The present study addresses an important knowl- edge gap, as the effects of prenatal and postnatal antibi- otic exposure on preterm infant gut microbiota have not, thus far, been characterized by high throughput sequenc- ing methods that provide sufficient coverage of the entire bacterial community.

Effects of low intensity and high intensity cycling with diesel exhaust exposure on soluble P selectin, E selectin, I CAM 1, VCAM 1 and complete blood count

Effects of low intensity and high intensity cycling with diesel exhaust exposure on soluble P selectin, E selectin, I CAM 1, VCAM 1 and complete blood count

In the current study, white blood cells, neutrophils and monocytes increased following exercise; the magnitude of the increase was exercise intensity dependent, but there were no effects of DE on the response. The finding that WBC and neutrophil counts increased with exercise intensity, without a further increase with DE exposure, suggests that acutely, DE may not initiate a systemic inflammatory response through WBC. The increase in WBC and neutrophils with exercise intensity is not surprising as acute exercise results in a biphasic response of blood neutrophils. Initially there is a rapid blood neutrophilia, followed by a second delayed increase a few hours later, and the response increases as exercise duration and intensity increase. 35 36 The initial increase

Title: A Survey on FEC Based Packet Loss Recovery Technique in Networks

Title: A Survey on FEC Based Packet Loss Recovery Technique in Networks

The first audio data is considered as Primary encoding and the subsequent transmissions are considered as secondary encodings. It is the sender’s choice that the secondary encodings is of the same encoding scheme or not usually secondary encoding will be of low bandwidth and low quality as compared to that of the primary encoding and basically depends on bandwidth requirements and computational complexity Erdol proposed short term energy and zero crossing measurements for secondary encodings because at the time of loss receiver interpolates the audio signal about crossing using zero measurements it can be coded compactly and is computationally cheaper but it covers only short period loss because of crude measures. Hardman and bolot proposed low bit rate analysis using synthesis codecs and full rate GSM coding which is computationally demanding and can cover the loss periods on internet[7]. If the primary encoding has low bandwidth and covers considerable power then the secondary encoding will be same as primary Eg: International Telecommunication Union (ITU) G.723.1 [6] codec which consumes a considerable fraction of today’s desktop processing power, but has a low bandwidth (5.3/6.3 kb/s).

Effects of chronic intermittent hypoxia, acute and chronic exercise on skeletal muscle Na ,K ATPase, buffering capacity and plasma electrolytes in well-trained athletes

Effects of chronic intermittent hypoxia, acute and chronic exercise on skeletal muscle Na ,K ATPase, buffering capacity and plasma electrolytes in well-trained athletes

spending ~ 20% of competition at high exercise intensities (Padilla et al., 2000). Flat terrain races are typically ~200 km in length, with large periods of time spent at low intensity with flat terrain specialists producing high absolute power outputs, and a corresponding high absolute oxidative capacity (Lucía et al., 2001). Mountain stages involve up to 200 km of racing and sometimes up to five or six mountain passes. Mountain stage specialists have a high relative power output and oxidative capacity (Padilla et al., 1999; Lucía et al., 2000; Lucía et al., 2001; Padilla et al., 2001). Compared to cyclists with a lower training status, elite cyclists have reached a high level of physiological adaptation, with a higher oxidative capacity, develop higher peak and sustained power outputs (Mujika & Padilla, 2001), and are more efficient (Coyle et al., 1991; Lucía et al., 2002). Elite cyclists do, however, strive for further physiological and performance enhancement, with further increases of even 1.5 % important for improved sporting performance (Hopkins et al., 1999). Two interventions used by elite cyclists to further enhance performance include altitude / hypoxic exposure and replacing a portion of their training volume with high intensity training (HIT).

Low intensity blue enriched white light (750 lux) and standard bright light (10 000 lux) are equally effective in treating SAD A randomized controlled study

Results are in line with those of Anderson et al. [16], who found that blue monochromatic low-intensity light (98 lux) was equally effective in treating SAD as broad- band white light at 711 lux with identical photon density in the 424-532 nm range. The short wavelength photon flux of these two conditions is highly comparable to the BLT condition of the present study. The current find- ings on exposure to low-intensity blue-enriched white light are also in line with the results of studies in office surroundings. It has been shown that sleep quality and alertness improved when workers spent their day in an office with blue-enriched white light with an intensity of 310.35 lux in the daytime instead of in the standard white (4000 °K) office lighting conditions with a mean intensity of 421.07 lux [29]. In a similar study, the stan- dard room lighting had an intensity of 345 lux and was compared to blue-enriched light with an intensity of 354 lux [31].
